Discussion Overview

The discussion revolves around the factors that determine the force between two magnets, specifically considering their lifting capacities and the conditions under which they interact. Participants explore theoretical scenarios and the influence of geometry and material properties on magnetic force.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether the force between two magnets would be stronger than both, or stronger than one but weaker than the other, depending on their interaction.
  • Another participant emphasizes that the situation is geometry dependent, highlighting the importance of the magnets' shape, orientation, and relative positions.
  • A different viewpoint suggests that if the magnets are in close contact, the maximum force possible would be observed.
  • One participant introduces the concept of magnetization, noting that if the smaller magnet can be magnetized by the larger one, the force could approach that of the larger magnet.

Areas of Agreement / Disagreement

Participants express differing views on how the force between the magnets is determined, with no consensus reached on a definitive answer.

Contextual Notes

The discussion does not resolve the assumptions regarding the conditions under which the magnets interact, such as their distance, orientation, and material properties.

If i have one magnet A which can lift(hold) 1kg(9,8N) and i have another magnet B which can lift 10kg(98N), what would the force between these magnets be?

I don't need an exact answer, but i do see to possibilities:

1: The force would be stronger then both the magnets
2: The force would be stronger than A, but weaker then B (somewhere in between)

Which one is it?

This is a very geometry dependent situation. It depends on the shape of the magnets and their orientation and relative positions with respect to each other.
 
I imagine that the magnets are in contact(very close) and that the fields around them are in such a way that the maximum force possible is observed

When a magnet picks up high mu iron, the iron gets the magnetization M of the magnet picking it up.
If the 1kg magnet has a locked in M, the force will be close to the average.
However (and more likely) if the 1kg magnet can be magnetized by the 10 kg magnet (just as iron is),
Then the force will be close to that of the 10 kg magnet.
 
Thanks:)
